Recently, girls sometimes talk and ignore me. Should I ask her why? I wonder if it's boring.

If you find that girls talk to you sometimes recently and suddenly ignore you, in fact, you don't need to ask her why. Chatting with you suddenly ignored you, so the reason is actually very simple, that is, chatting with you is too boring for him to feel. You have a boy's sense of humor and sense of humor, which makes him feel that you can't find the topic or adjust the atmosphere by chatting casually, so he doesn't think you are bored, just that chatting with you makes him feel bored.
